Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in attached drawing 1,2 and 5, the present invention provides a kind of medical accelerator therapeutic bed track pedestal, track pedestals
Including cup dolly 1 and base body 2.
Wherein, the cup dolly is an annulus formed steel base, and the melt pit pre-set is embedded in by tool locating
It is interior.The bottom surface of melt pit needs to guarantee basic horizontal, and depth is consistent with cup dolly height, so that the cup dolly center line of installation
It is essentially coincided with the vertical line for crossing accelerator isocenter point.By the melt pit gap concrete around pedestal after the installation of cup dolly 1
10 fill and lead up, and 1 bottom surface of cup dolly is equipped with the circular trough 8 matched with the mounting surface 9 of 2 bottom of base body, 8 central point of circular trough
It coincides with cup dolly central point, as long as base body 2 is mounted in the circular trough 8, the location of the core of base body 2
It completes, without in addition adjusting.It is provided with several uniformly distributed threaded holes on circular trough 8, is fixed on circular base for base body 2
On seat 1；
Base body 2 is a similar pot cover shaped cast steel disk laid flat, has structural rigidity good and to install contact surface steady
The advantages of；Overall processing forms all on base body 2 for center positioning hole 4, circuit orbit 5, mounting surface 9 and adjustment hole, center
The verticality of the concentricity and circuit orbit 5 of location hole 4 and mounting surface 9 is all guaranteed.
Center positioning hole 4 is at base central position i.e. the top of pot cover shape, the edge and cup dolly of base body 3
1 circular trough 8 matches, and plays the role of centralized positioning and support treatment bed body construction weight, the cavity of 2 bottom of base body
Space is provided for installation cable and control component.
Wherein, the internal point that center positioning hole 4 is turned round as therapeutic bed plays the centralized positioning to therapeutic bed bed body and erects
Histogram to limit function, the polished surface of 4 upper and lower ends of center positioning hole can be used as track foundation level degree adjusting reference
Datum level.
The outer rim of base body 2 is arranged in circuit orbit 5, finishes on the basis of flange at base body edge,
Orbital plane flatness with higher and the depth of parallelism relative to mounting surface 9.
